Blog Post Text Box

Hello @LULU3, You might want to check if there are any spacer blocks on either side of the text block that could be preventing it from stretching to full width. I've attached a screenshot for reference to help you identify this in your layout.

And if there are no Spacers, you can add this code:

1. Navigate to Pages > Website Tools > Custom CSS.
2. Paste the code into the CSS editor.
3. Hit Save and you’re done

@media only screen and (max-width: 640px) {
    .sqs-layout .sqs-row .sqs-block:first-child {
        margin-left: 0% !important;
        margin-right: 0% !important;
    }
}
